Special hints

Bait doped fiber amplifiers is a high-end professional equipment and its operation of the

installation must be performed by professionals, and read this manual carefully before

operating, in order to avoid damage to equipment due to misunderstood operation, or

causing accidental injuries to operators.

When working in optical fiber amplifier, located at the rear panel of the optical signal

output adapter will have invisible laser beam shooting out the optical signal output port

should be avoided on the human body, outlet should not look directly at the light with the

naked eye, so as not to cause permanent harm to the human body, the human eye!!!

Equipment in power before, should first confirm that the earth terminal of the Cabinet and

the power outlet is reliable earthing (grounding resistance should be 4 ω), in order to avoid

static damage to the laser device and prevent the Cabinet charged that cause harm to the

human body.

To ensure device can long-term stability of work, in voltage does not stability or voltage

waveform poor of area, recommendations user for device configuration dedicated of

exchange regulator power, has conditions of user more can configuration does not

continuous regulator power (UPS) system; in environment temperature changes too large

or room environment poor (device of ideal work environment temperature for 25 ℃) of

area, recommendations user for device configuration dedicated of air conditioning system,

to improved device of work environment.

VII. Installation and commissioning 7.1 opening checks 1. the equipment in front of the out of the box make sure packaging intact; if outsourcing with damaged or water marks, please contact your local dealer or the carrier immediately. 2. check upon opening the box the packing-slip if requested in accordance with an inventory of equipment and accessories inside the box, if you have any questions please contact your local dealer or call the company. 3. upon opening the box and if you think the device is damaged, do not power on, in order to avoid serious damage to the equipment or cause accidental injury to the operator and immediately contact your local dealer or call the company. 7.2 instrument and tool 1. optical power in mind one 2. digital multimeter; 3. standard fibre test jumper one (FC/APC or SC/APC); 4. ethanol and a number of medical absorbent cotton; 7.3 installation steps 1. before you begin installing the device, please be sure to read the user manual carefully, and according to procedures set forth in the user manual for installation and commissioning. Note: because no can be carried out in accordance with the user manual of practice for installation and commissioning of equipment as a result of man-made damage and all other consequences, our company will not be responsible for any liability or no free warranty. 2. remove the device from its packaging, rack mounted, and reliable grounding device (grounding resistance should be 4 ω). 3. use a digital multimeter to check supply voltage, make sure the voltage is to meet the requirements, and the keys to confirm that the switch is in the "OFF" position, you can power cycle connected devices. 4. under display message, the access light signals, and then rotate the key to switch to "ON" position, observe the status of the front panel led, after the PUMP working condition, such as the light turns green, device access to normal working condition. At this point you can press the menu button on the front panel to view the operating parameters of the equipment. 5. test jumper with standard fibre optical signal optical power meter connected to the device's output, the output optical power measuring device, confirming its output optical power and the front panel display the same value, and the nominal value has been reached. (When measuring optical power, optical power meter should be recognized under the 1550nm wavelength measurement document, confirm that the fiber optic test jumpers to match standard test jumper, Union joint surface and pollution-free. ) Removal of standard fibre optic test jumpers and optical power meter, devices connected to the network. At this point, the device has finished installation and commissioning.

VIII. after-sales service 1. I promise: products are free warranty for 13 months (to paste the factory serial number on

the side of the device is identified by the factory starting time of day), and lifelong maintenance. Due to user misuse or irresistible natural factors caused by equipment failure, we will only be responsible for the maintenance, material costs and charge the appropriate fee.

2. If the device fails, you should immediately contact your local dealer, or call our customer service center.

3. Fault device requires action by professional technicians on-site, so as to avoid equipment damage.

4. Special Note: for devices that was to open the maintenance by the user, our company will not be free warranty, only to the warranty and reasonable maintenance costs and material costs will be charged.

Cleaning and maintenance method for fiber optic connector And a lot of times, we will drop light power outlet misjudgments for optical equipment failure, the actual fiber optic connector may be caused by dust or dirt, pollution, just proper cleaning and maintenance of fiber optic connector, you can troubleshoot. Below introduce operation method of cleaning and maintenance of fiber optic connector. 1. power off the device, carefully unscrew the fibre on activities from the adapter connector 2. with texture good lens tissue or carefully with a degreasing alcohol cotton light connector

cleaning; such as degreasing alcohol cotton cleaning, cleaning is complete, also 1-2 minutes, let dry alcohol flavor of the active connector surface

3. cleaning out fiber optic connection socket, access optical power meter, measuring output optical power, to confirm that the fiber optic connector has been cleaned.

4. clean the fiber optic connector back to the adapter, should pay attention to appropriate, in order to avoid too much force lets the adapter internal ceramic pipe rupture.

5. fiber optic connector after cleaning, the output light power is not normal, you should remove the adapter, unscrew another connector to clean it inside the machine; such as cleaning after the optical power remains low, at which point adapter might be contaminated, cleaning with the adapter. (Note: use caution when you remove the adapter operation in order to avoid damages fibers inside the machine. ）

6. dedicated compressed air available for adapter cleaning or degreasing cleaning alcohol cotton section. With compressed air cleaning, compressed air nozzles of gas tank at the adapter of ceramic pipes, ceramic tubes blowing compressed air into clean; with fat alcohol cotton cleaning, carefully into the alcohol cotton ceramic pipe cleaning. Attention alcohol cotton into the direction of articles should always be consistent, otherwise may not be able to reach the ideal cleaning effect.

Pay special attention to A. in the cleaning operation of fiber optic connector should be avoided with optical connection

diagram on the human body or human eyes, so as to avoid causing wing damage on the human body or human eyes permanently burn!!!

B. installing fiber optic connector, force should be appropriate, failure to do so may cause the adapter in the ceramic fragments. Ceramic Tubes once the fragmentation, the output light power will drop significantly, turning it slightly and fiber-optic connector, the output light

- 12 -

power will be significantly changed. C. any operation on the fiber, without turning on the pump laser, or high power output causes

the output fibre connector is burned out, thus giving rise to the output power is reduced. Such as equipment changes lead to a section in this manual do not match, are subject to change without

notice.
